SPECIFICATION forming part of Letters Patent No. 424,046, dated March 25, 1890.

Application filed August 24, 1889. Serial No. 321,894. (No model.)

To aZZ whom it may concern: I

Be it known'that I, IVALTER BULLARD, of Chico, Butte county, State of California, have invented an Improvement in Baling-Presses; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to the class of balingpresses; and it consists in the constructions, arrangements, and combinations of parts hereinafter fully described, and specifically pointed out in the claims. I

The object of my invention is to provide a compact, eifeotive, and rapidly operating press.

Referring to the accompanying drawings for a more complete explanation of my invention, Figure 1 is a side elevation of my balingpress. Fig. 2 is a plan View of the power portion. Fig. 3 is a horizontal section of the balin g portion. Fig. 4 is a vertical section of the baling-chamber, showing the threadingneedles and frame in elevation. Fig. 5 is a vertical longitudinal section showing the follower on its forward movement. Fig. 6 is a sectional view showingthe follower onits backstroke and operating the topdoor of the feed chamber. Fig. 7 is a detail of thelatch mechanism at one end of the top door. Fig. 8 is a plan of the power-mechanism connections. Fig. 9 is a horizontal sectional view of the power-wheel and its trip. Fig. 10 is a vertical section of said wheel and trip. {Fig 11 is a vertical longitudinal section ofjthe balingchamber, showing the end door or cap and means for fastening it. Fig. 12 is a detail view of the flap-operating device. Fig. 13 is a detail showing the means for locking the end door disconnected.

A is the baling-press frame,'in the forward end of which is the baling-chamber B, behind which is the feed-chamber C. The whole frame A is mounted at an incline, its forward end being supported upon wheels a. Within the frame A is the follower D, Figs. 3, 5, and 6, having cross-heads, the ends 61 of which project through the sides of the press in elongated slots therein, whereby the follower moves back and-forth, traversing the feedchamber and entering the baling-chamber. This movement of the follower is efiected by means of toggle-levers E, which are pivoted to the projecting ends (Z of the cross-heads of pivoted to the frame.

the follower, and are also pivoted to the frame, and these toggle-levers are operated by means of the main power-chain F, the branches f of which, passing over suitable guide-pulleys f, extend to and are connected with the toggle-levers. By drawing on the chain F the toggle-levers E are straightened, so that they force the follower forward with great force. The follower is returned by again bending the toggle-levers, this movement being efiected by means of the branches g of the cable G.

The feed-chamber C has a top door 0, and above this is built the feed-hopper H, for which said door serves as a bottom. In the side walls of this hopper are me de the curved slots h, and from the sides of the door project the studs 0 through the curved slots of the hopper, as shown in Figs. 5 and 6, and these studs are connected with guide-braces 0 Fig. 1, on the outside. The studs do not touch the sides of the curved slots at all, but are pivoted in the arms or braces outside the hopper. The opposite ends of these braces are The door is adapted to be turned through a half-revolution and reversed, end for end, by the follower itself,.

so as to dump its load into the feed-chamber. This operation is accomplished by means of the mechanism shown in Figs-5, 6, and 7, to which reference is now particularly made. At its forward end the door 0 is held down normally by a hinged flap I, controlled by a spring 2', which holds it out to place over the end of the door. The rear end of the door is held down by a hinged flap J. In the back of this flap is made a socket j, partially covered by a flange or plate j, Figs. 7 and 12, and into this flanged socket fits the hooked end of the latch K, pivoted by means of arms is to an upright bolt Figs. 5 and 12. Against the back of the lower arm 70 a spring 10 presses, causing the latch K to engage the flange or plate j as the flap J drops down to it.

Pivoted at Z is a bell-crank lever L, one arm of which is provided with a small anti-friction roller Z, bearing under the rear end of the door a. The other arm of the bell-crank lever carries a stud Z over which is freely slotted theend of a short lever Z which is pivoted at Z to the bell-crank lever L. A cord or cable 01' connects the follower with the short lever 1". Upon the top of the follower close to each end is a catch-piece (Z and the ends of the door 0 are grooved or notched out to engage with these catches. The operation of this mechanism is as follows: Suppose the door 0 be in its place, as shown in Fig. 5, and the follower D, advancing through the feed-chamber O, pushing the material which is in said chamber before it into the baling-chamber as it moves forward. The flaps I and J hold the doorc down. Now, when the follower is nearly home the cable or cord (1' becomes taut, and pulling upon the pivoted short lever Z causes said lever to move. Its first movement does not affect the bell-crank lever L, to which it is pivoted, because it is freely slotted over said lever, and this first movement merely has the effect of causing the short lever Z to come in contact with the lower arm 75 of the latch K, thereby turning said latch about the bolt as a center and removing its hooked endfrom the flanged socket j of the flap J, thereby releasing said flap. The further movement of the short lever Z now begins to affect the bellcrank lever L, and turning it about its pivotal center raises its roller Z under the rear end of the door 0 and raises saidend slightly, depressing its forward end, as shown in the dotted lines in Fig. 5, and allowing the flap J to fall into the notch or groove in the back end of the door, thus holding the door in position while the follower starts back. The follower now returning, its catches (Z engage the forward notched end of the door 0, said end having been thrown down into its path by the raising of the rear end, and as the follower moves back it pushes the door before it, so that turning about its side studs 0, which travel in the curved slots h of the feed-hopperH, said door assumes first the position .shown in the dotted lines of Fig. 0, and then the position. shown in the full lines in said figure, and remains there until it is pushed down again -by ,hand, having thus turned through a half-revolution and reversed itself end for end. In this movement it drops the load which was on thetop of it into the feedchamber, and the follower is then ready to move forward again,the hinged flaps I and J having sprung to place to hold the door firmly.

The base of the feed-chamber C is provided with a-movable floor M. This floor is hinged by its sills to the frame at m and is adapted to move up in line with the bottom of the frame to contract the feed-chamber and to drop down to a horizontal plane, as shown in to the baling-chamber, and when the follower has returned and turned the top door, as be fore described, the material is dropped into the feed-chamber and rests upon the floor M, which is then in the position shown in Fig. 6. This dropping of the floor takes place as follows: A pivoted flap on has a spring m to hold it in place with its upper end under the free end of the fioor M, and provided with an upwardly-projecting flange m Pivoted to the bottom of the follower is a toe-piece (1 Now, when the follower is moving forward, as shown in Fig. 5, the toe-piece (Z drops down through a slot (1 in the base of the balechamber and comes in contact with the flange m of the holding-flap m and pushes said flap forward from under the end of the floor M, which thereupon drops of its own weight from the position shown in Fig. 5 to the position shown in dotted lines in said figure and in full lines in Fig. 6; but it is obvious that the floor M must be closed again before the follower moves on its forward stroke, so as to raise all the material into the feed-chamber and confine it in said chamber in front of the follower. This movement of the floor is effected by means of the cord or cable N, which is properly directed and attached to levers n, pivoted to links it, and connected with the floor M. Now, by pulling on the cable N the levers n are operated to throw the floor up to position, where it is held by the spring-controlled flap m.

In Fig. 4 I show a rectangular frame 0, which embraces the frame A at the entrance of the baliugchamber. The sides of this frame 0 are mounted in suitable sockets 0 on the sides of the baling-press, so that the frame may be moved up and down. The bottom bar of the frame carries the vertical needles 0', which extend up through slots 1) in the floor of the baling-chamber and are adapted to pass through the grooves (Z of the follower and through slots 0 in the top of the balechamber. The baling wires or ropes are threaded to these needles, and the needles are raised by raising the frame by hand, so that they carry the ends of the wires up into position to be tied, in a manner prescn tly described.

To the end of the baling-chamber B, at the upper end of frame A, is hinged at its top the end door or cap V, Fig. 11. This cap is fastened and released as follows: Under it are bolted the hooks c. is a rock-shaft mounted in spring-arms 20 under the end of the balingchamber and projecting therefrom, said shaft having a crank-lever w on one end. The shaft is also provided with projecting lugs 10 Now, after a bale has been tied and the follower withdrawn the lever 10 is raised to rock-shaft and brings its lugs up against the hooks n, which engage the shaft and hold the cap. These lugs pressing against the hooks 'u depress the shaft \V, its spring-arms w yielding, so that the shaft leaves the hooks and thus frees the cap. As the material for IIO the next bale enters, the bale previously pressed and tied is pushed out by it, thus raising the cap. When the bale falls from the press, the cap drops byits own Weightand fastens itself again by hooking onto the rockshaft. I I

The passage of the wires or ropes for tying the bale is as follows: The bottom of the baling-chamber has slots 1), and its top has slots 29. The cap V has Verticalslots r, and the follower D- has grooves 61 on its front. One end of the wires or ropes is passed through the bases of the slots 2) of the cap,

and along in the slots b of the bottom of I the baling-chamber, and through the eyes of the needles 0'. The other end is passed through the tops of the slots 4; of the cap and out through and along the slots 5 in the top of the baling-chamber, and is tied to the first end, which has been raised through the slots d of the follower to the top by the needles 0.

In Fig. 8 I have shown the continuation timbers P of the frame A, said timbers di-" verging rearwardly and having mounted between their separated rear ends the main power-wheel Q, which is adapted to be operated by a power-lever q, Figs. 1 and 2, to the end of which the horses are attached. The rim of the wheel is enlarged and provided with a circumferential groove, as shown in the section, Fig. 10, and upon this enlarged rim is fitted and adapted to slide a bracket R, in which is pivoted at r a trip-lever r,

. ing a spring 8. tached the main operating-chain F, which having an extended base r which extends down and travels in the groove of the wheel, and a cross-head top r Pivoted in the bracket R at its other end is a trigger S, hav- To the trip-lever r is atconnects with the toggles E, which operate the follower. Transversely mounted on the frame P is a rod or guide 10, on which is mounted and adapted to slide a collar 10', held in place and controlled by a link 19 operated by a lever 19 Fig. 8. The collar 10. stands in the path of the trigger S, as shown in Figs. 8 and 9. In the groove of the wheel Q at one place is firmly fixed a contact-block q, Fig. 9. by the lever q it does not afiect at first the movement of the bracket R and its attachedparts; but when the"contact-block q of the wheel comes around to and is brought into contact with the base of the trip-lever r, as shown in Fig. 9, then these parts are picked up and carried with the wheel, and,

7 moving around with it, draw on the chain F,

thereby causing the forward movement of the follower and driving it home; but at this time the'trigger S, approaching the fixed collar p, as is shown in Fig 8, comes in contact therewith, as is shown in Fig. 9, and is bent over, thereby relieving its lower end from the base of the trip-lever r, and said trip-lever being free turns, about its pivotal center as the stop-block q passes it, so that the wheel moves on without carrying the trip any far- Now, whenthe wheel Q is turned ther, and therefore the tension on the chain F is released and the follower ceases to be operated. When the follower is drawn back by the means presently to be described, the bracket R and its connected parts are drawn around on the rim of the wheel Q by the chain F until, coming in contact with the fixed stop g on the opposite side, as is shown in Fig. 9, the trip-lever is thrown up to a vertical position again, and the trigger S, actuated by its spring 3, is turned into position and again holds the trip-lever.

- The drawing back of the follower, as before stated, is effected by means of the chain or cable G. This chain or cable, as is shown in Fig. 8, passes over a. guide-pulley g and is attached to a pivoted arm T, connected with the frame-timbers P. This arm extends into the path of a fixed pin or stud g under the lever q, and at the proper time the contact .of this stud with the arm T swings said arm and pulls upon the cable G, so as-to return the follower.

The upward movement of the floor M of the feed-chamber is effected, as heretofore described, by the cable N. This cable, as will be seen in Fig. 8, passes backwardly over the guide pulley g, and is attached to the end of-the swinging bar or arm U, the projecting end of which lies in the path of a second pin I or stud q? under the lever q, and when the contact of said pin or stud with the arm U is effected-the cord or cable N is pulled upon and raises the floor.

The object of having the collar 19' adjustable on its rod 19 is to vary the positionat which the trigger S comes in contact with it. Thus on the final pressure of the bale it is desirable to let the follower move closer home before it is released by the trip, and this is done by setting the collar o -farther back, so

with it so soon. I
